-### Note about zkSync
-
-This repo does not support deploying contracts on zkSync, which is why `yarn deploy` will fail.
-Instead, after deploying the proxy using `yarn deploy-data-feed-proxy`, you can test the proxy by reading from it directly.
-See the command below, but use your own `NETWORK` and `PROXY` values.
